Title: Input limit circuit
Inventor: MORITA MAKOTO
IPC: G05B19/02
Filed: 1987-03-30
Abstract: PURPOSE:To shorten the minimum acceleration/deceleration time and at the same time to reduce the cost for an input limit circuit, by feeding the output signal voltage of a D/A converter back to an arithmetic circuit to calculate the difference between this fed-back voltage and the input signal voltage by an arithmetic circuit and performing a time constant process according to said difference by an A/D converter. CONSTITUTION:The output of an arithmetic circuit 11 is given to an A/D converter 14 of low resolution (8 bits, etc.). The converter 14 converts the input voltage corresponding to the arithmetic result (difference) received from the circuit 11 into a digital form and applies it to a control circuit 15. The circuit 15 carries out the addition/subtraction with a designated time constant against the output value (digital value to frequency) under output and outputs the result of this arithmetic to a D/A converter 16. The converter 16 has the resolution of 12 bits, for example, and converts the input given from the circuit 15 into an analog form. Thus the minimum acceleration/deceleration time can be shortened at a low cost.

At this time point, even if an operator releases his hand from the input pen P, since the tip A of the engaging part 13 of the lock member 10 is fitted into the stepped part 14b, the holding member 4 comes not to return from its position. At the time of using the input pen P, when the input pen P is further pushed in, the tip A of the engaging part 13 of the lock member 10 is pushed up along a slant face 14c, and in connection with a motion of the holding member 4 which moves together with the pen by energizing force of a spring 8, the tip A of the engaging part 13 gets on the horizontal plane 14a, and the holding member 4 is pulled back.

Title: Dust collecting device
Inventor: YANO JIYUNICHI
IPC: B03C3/00
Filed: 1980-06-09
Abstract: PURPOSE:To magnetize granular materials in gas flow, give flocculation effect and improve the removal performance of ultrafine particles in a dust collecting part by attaching a magnetic field generator to the front stage of an electrostatic dust precipitating part. CONSTITUTION:A magnetic field generator 6 is provided in the outside cicumferential part nearer the inlet 1a side than the position of an electrostatic dust precipitating part 2 consisting of the discharge electrode body 3 and a dust precipitating plate 4 in a duct 1. When dust-laden gas is introduced through the inlet 1a, the magnetic particles in the dusts in the gas flow are magnetized while the gas flow is flowing in the magnetic field by the generator 6 and consequently the granular materials flocculate each other, thereby resulting in increased grain sizes of the granular materials. When such gas flow is sent to the part 2, the granular materials 7 are charged by the corona discharge generated near the electrode body 3, and stick on the plate 4. According to such device, almost all the granular materials in the gas flow sent to the part 2 have relatively increased grain sizes and therefore dust collection efficiency is improved.
